I'm thinking to connect a IMX258 which is a 13mp image sensor. I'm wondering if I could capture the 13mp picture just via the CIF? the processing, e.g. de-Bayer, will be done with the software.

Hello, the limitation for RV1106 ISP is 5M at 30fps, and the maximum resolution of Bayer CIS is 3072x1728. Theoretically, higher resolution RAW images (such as the 8M@15fps configuration provided by Rockchip officially) can be processed by reducing the frame rate. However, there is definitely a limit to the maximum resolution of the ISP (Rockchip has not provided this information and it may require calculating the ISP's clock frequency to determine).

thank you very much for your reply. Would you be able to confirm if the pixel data can also be captured right after the MIPI interface and before the ISP? If so, would there be any limitation in terms of the capture size for the mipi_cif part? Regards

It is theoretically possible to directly obtain the RAW image from CIF. However, Rockchip's official has not provided the data of the maximum supported resolution. The driver may detect this and impose restrictions.
